Length gains and hair growth, penetration?

Hi, never thought anything about this until you started the subject. I have gained about 1 1/2” and now I see about 1” area of hair on my shaft. I keep it trimmed because I have a pull regularly with a water vac pump

Okey! I usually trim/shave everytime i’m going out for party, just in case you know ;)Or when i need to seal the bathmate.

But this hair idea i got, concerned me. I always have battles against myself to find out a good conclusion about the gains i have made in PE.When i don’t have the experience enough to try the methods myself i came here asking for help from others that maybe have experience on the subject ;)But it seems hair doesn’t make a difference so far accordingly to the members.
